lie it know it that l, SETH \Ynlnnirln, a citi- Zen of the t'nited States of America, and. a resitlent of tastleton, county of l'tensselaer, State of New York. have invented,certain new and useful improvements in Delivery Mechanism for l oltling-Machines and the Like if which the following is a specificalion, reference being had to the accompanying drawing forming a part thereof.

\l invention relates to improvements in delivery mechanism for folding machines and the like. aml particularly to means for re-- ceiving packages of folded and interl'olded sheets from mechanism such as is disclosed in a co-pending application Serial No. 282,151. filed October ltlth. lSltlS.

My invention consists, first, in the combination with a receiving box, if an improved form of resistance device therein, arranged to \'ieltiingl resist articles. as the) are fed into tl'e box, the amoint. of such resistance being *eadily adjustable, together with means wl-erebv such resistance is caused to be uniform for the whole width of the receiving box: second. in a supplententar resistance device arranged t be brought into play when the prima y resistance device is tetnporatilv out of Lise. .tt such times for instance as when article :zr-e being removed from the receiving liox. t1 it'd. in means for facilitating the removal of articles front the receiving box: and. lastly. my invention consists in certain novel details of construction and combinait.

set forth.

in order that m v invention may be full i understool. i will now proceed to describe mechanism in which my invention is embed: icd, having reference to the accompanying drawings illustrating same, and will then point out the novel features in claims.

In tlte drawings: Figure l is a top view of delivery mechanism embodying nrv inventi n. Fig. 2 is a view in transverse section through the same substantiall t' upon the line 2 2 of Fig. lv Fig. .l is a detail sectional "low at one eml of the receiving box, showing the means for sttj)]l-- 1tittg' a removable ta ble. mechanism shown in Fig. l. in longitudinal section upon the line 5 5 of Fig. l. but with the end portion of he rteiviqg iwx how-nits swung Fig. 5 is a view thereof suhstantiallv n of parts a will hereinafter be more fully j f engagement of tire 7 2t! will enforce parallel movement ot the foll tg. t is a view in side elevation of the downward out of operative position, and a removable table shown as in position, in place thereof.

l or purposes of the present description, I will refer to the delivery meeha-nisn'i as adapted to receive folded and interfolded sheets of paper to form interl'olded paekages,.tl1ough it will be understood thatthe same is intended in no sense as a limitation on the use of the ineein'tnism.

in Fig. 5 l have shown a. small portion of a folding machine. including upper and lower folders 1t), 11, which operate to fold and interlold paper units into package form; and a. few of said units so folded are also illustrated at 12 in said iigure. These units 12 are r ceived in the receiving box, herein designated as a whole by the reference character 13, the rear-most sheet being engaged by a follower it. In Figs. 1 and at of the drawings this follower is shown in a position at about twothirds of theway toward the left of the receiving box, and in Fig. 5 it is shown as removed from the main portion of the box altogethta' (for a reason to be presently ex-v plained), but it will be understood that, in first starting up, the said follower ispushed forward to a position near the mouth of tht receiving box, and is forced farther and farther back by the package as it increases in. size in the box. \Yhen in such a position as shown in Figs. l and 4 of the drawings, the- 5 whole of th" pace from the mouth to the face of the follower it is supposed to be filled with folded and interfoldtal sheets comprising the package or packages.

The receiving box comprises a base 15 and ,sitlts to. The box is open at; opposite ends, as will be seen by reference to the drawings The follower H is arranged to slide nponthe base 15 between the sides 16, occupying the entire space widthwise between the said sides 10. and the said follower is provided with a shaft- 17 journaled in bearings 18, said shaft having at its extreme ends pinions 19, which engage with longitudinal stationary racks 2U secured to the side walls 16. The pinions 19 with the racks lower 14-. preventing the same froni assuming any position other than a position at right angles with respect to the walls of the box and will hence enforce parallel movement 0 the interfolded sheets as they advance. The

-;ranged to surround the shaft 17, and prowill then vary the resistance oliered by the follower leis further provided with a friction device 21 arranged centrally thereof, said friction device being in the form of a clip arvided with'means in a screw 22 for adjusting the pressure of same upon the said shalt- 17 It will be understood that, as the friction devine is tightened upon the shaft 17, rotation of the shaft will be resisted, and in this manner movement of the follower along the resistance box will be similarly resisted, becansethe said follower can only move as the shait'revolves. Adjustment of the screw 22 followerl lto any predetermined extent, and,

in this mannenjnst the precise amount of resistance desired to be oi'l'ered to the advancing package or packages in' the box may readily be produced.

.'l he foregoing resistance means in com.

munication 'Wlth the, receiving box consti tutes the first part of my invention herein, and may be used, if desired, independently of the supplemental resistance means which Lwill now describe. This supplememal resistance means may be m 'nvenienLly employed for the purpose of temporary use while a certain number of the sheets are removed from the receiving box, and until the main follower is a ain brought up into use. The supplemental means comprises two raeks 23 arranged to travel along the upper edges ofthe receiving box sides in, pinions 24 in mesh with said racks, a shaft 25 arrying said pinions, siaiionary bearings 26 for the said shaft, and a removable finger bar 27. The racks are an': n1ged to move lre'ely 'backwardand forwardby reason of their engagement with the pinions 24 when-the said shaft 25 1s roLaied, and the said shaft may readlly be rotated by means of a hand wheel 28 secured therezo at oncend for SUCIIPUIL,

pose. The bearings 26am arrangrdas frietion bearings, being adapted to grip the shaft 25 .upon adjustment of ihe lJUliS 29, in l'rir-Lion bearing 21 of the follower 14 is arrangrd upon tUljllSillH-Ht ol' the screw 22, to grip the shaft 17.

The linger bar 27 is removable, sai

ber, il-leends of whirh are arranged to be reeeived frvelyin reresses 30 in ihe said rarks 23, and dependent fingers 31 arranged .0 project downwardly irno ihc row-lying box in the path ol 'the mzuerial rereivvd ihr-reiii.

, hen it is drsired io move a predeivr mined number of sheets lrom .hv box, ibe racks '23 will be moved all 'the way lorward as far as they will go, and he linger bar will then be dropped lllH) position Will the lingers between the front sheet ol the parkage 1o be removed and ihe rear s'llr il ol' who :idvanring package. Thesupplrmrniary resislanro means will now act to resist the onward movement of the incoming sheets, while the d 'lingr-i" bar Comprising a transverse carrying mom-- l l i l i primary resistance device may be pushed out of the way and the sheets contained between the primary and secondary resistance devices removed by hand. Then the primary resist anee device, or follower 14, as it has been called, may be pushed up into place immediately behind the fingers 31 of the stationary device, the said finger bar 27 being then removed and the operation continued as before. It is understood, of course, that the device is normally operating with the finger bar 27 removed, and that the said. linger bar is only put into position when the follower 14 is temporarily out of use. In order to guide the finger bar to its position in the rec esses 30,1 have provided uprising fingers 32, said fingers secured to the ranks 23, and the lower portions thereof forming ('aps'for the said recesses 3i), will be readily understood by reference tot jie drawings. v
